“Our study demonstrates the high sensitivity of [gallium Ga-68 dotatate] in the localization of [ectopic Cushing’s syndrome], for both occult primary tumors and metastatic lesions,” the researchers wrote. “Importantly, the use of [gallium Ga-68 dotatate] impacted clinical management in 64% of patients with [ectopic Cushing’s syndrome] overall.” The researche […]

The 11th annual Pituitary Day will take place on October 19, 2019 Patients living with pituitary disorders can hear lectures from our pituitary specialists, see movies of pituitary surgeries and hear from other patients about their experience living with pituitary disease and undergoing surgery.

Cynthia is from Ruckersville, VA. She is testing for Cushing's due to many symptoms. tested for CD because after exhaustive research on AVN (Avascular Necrosis) related to other diseases. I have four known areas of AVN & after seeing the symptoms of CD, I realized may have this. I also have numerous other diseases Lupus, Sojgrens, Hypothyroid, High […]

Today is the Thirteenth Anniversary of my kidney cancer surgery. These thirteen years have been bonus years for me. For my cancer stage, the 5-year survival rate was 81% and I’ve made it more than twice that long – so far.

Kathy was diagnosed with a pituitary tumor in 1991. At the time the only symptom she was aware of was a severe headache. She had a transsphenoidal resection followed by radiation therapy for 23 days. They said they could not remove all of the tumor.

Sadly, we lost another Cushing’s patient on Friday, May 9, 2014. Melinda was a member of the Cushing’s Help message boards since Jun 24, 2007. She was only 25 and left behind a young son and many loving family members.

He died of a presumed heart attack. September 19, 2015 he said "'I was diagnosed hypertensive way back when I was 20. The condition remained for years, and became more acute with my cushings pit tumor. I still have high blood pressure, partially teated with three meds. I'll have to consult my doc and see if this may also be an issue."

'My name is Caroline and I dont post often but have met a few of you guys and read the board regularly, it has definitely been a godsend to cushies everywhere. The reason I am writing tonight is I have just received devastating information about a dear friend of mine, and a woman some of you may have met during testing. Her name is Kathryn Miller and sh […]

Patients with growth hormone deficiency due to nonfunctioning pituitary adenoma experienced excessive morbidity due to cerebral infarction and sepsis regardless of whether they received long-term GH therapy, whereas treatment was associated with a normal incidence of type 2 diabetes, despite higher BMI and more severe hypopituitarism in treated patients, according to findings from an observational, registry-based study.

“Although growth hormone replacement therapy is well-established and reverses most of the features associated with GH [deficiency], one of the safety concerns is the reduction in insulin sensitivity and the potential risk of developing type 2 diabetes mellitus,” Daniel S. Olsson, MSc, MD, PhD, professor at the Sahlgrenska Academy Institute of Medicine at the University of Gothenburg, Sweden, and colleagues wrote in the study background.

Studies examining whether there is an association have produced mixed results, the researchers wrote, and it remains unknown to what extent GH deficiency — and GH therapy —contribute to the development of type 2 diabetes and other comorbidities, including cerebral infarction, malignant tumors, myocardial infarction or fractures.

Olsson and colleagues analyzed data from 426 patients treated or followed for nonfunctioning pituitary adenoma between 1997 and 2011, selected from the Swedish National Patient Register. Researchers assessed information on tumor treatment, hormone therapy, antihypertensive medication, BMI and duration of GH therapy. For patients with type 2 diabetes, researchers assessed HbA1c values, insulin treatment, oral antidiabetes therapies and lipid-lowering therapies. Researchers followed the cohort through December 2014 or until death. Patients were stratified by use of GH therapy. Researchers calculated standardized incidence ratios (SIRs) based on the observed number of comorbidities among patients with nonfunctioning pituitary adenoma vs. the expected number of comorbidities in the background population.

Within the cohort, 207 patients received GH therapy (145 men) and 219 did not (129 men). Median duration of GH therapy was 11.7 years; mean age at diagnosis was 56 years for treated patients and 65 years for untreated patients. Median follow-up time for treated and untreated patients was 12.2 years and 8.2 years, respectively.

Incidence of cerebral infarction was increased for the whole cohort regardless of GH therapy status, with an SIR of 1.39 (95% CI, 1.03-1.84), and was most evident among 97 patients who underwent radiotherapy, in which 19 cerebral infarctions occurred vs. the expected number of 9.8 (P = .011).

“The study showed an increased overall incidence of cerebral infarction in patients with [nonfunctioning pituitary adenoma] compared to the general population that was related to previous radiotherapy, but not to GH [replacement therapy],” the researchers wrote.

Incidence of myocardial infarction was similar for treated and untreated patients, with SIRs of 1.18 (95% CI, 0.73-1.8) and 1.23 (95% CI, 0.82-1.78), respectively. Incidence of receiving medical treatment for hypertension was also similar between groups.

In assessing incidence of type 2 diabetes, the researchers found that the SIR was higher among untreated patients (1.65; 95% CI, 1.06-2.46) vs. treated patients, who had an SIR similar to the background population (0.99; 95% CI, 0.55-1.63). Treated patients with type 2 diabetes had higher BMI vs. untreated patients with type 2 diabetes (P = .01), according to researchers, and glycemic status was similar among treated and untreated patients.

The incidence of sepsis requiring hospitalization was also similar between treated and untreated patients, with rates for both groups close to double that of the background population (P < .001). Incidence of malignant tumors was not increased for treated or untreated patients when compared against the background population, according to the researchers. – by Regina Schaffer

Adult patients with severe growth hormone deficiency previously treated for acromegaly saw an increased fracture risk after 6 years of growth hormone replacement therapy, whereas those previously treated for Cushing’s disease did not experience the same risk, according to a recent observational study.

Nadege C. van Varsseveld, MD, of the department of internal medicine at VU University Medical Center in Amsterdam, and colleagues analyzed data from 1,028 patients with previous nonfunctioning pituitary adenoma (NFPA; n = 783), acromegaly (n = 65) and Cushing’s disease (n = 180), identified through the Dutch National Registry of Growth Hormone Treatment in Adults, a nationwide, long-term surveillance study in patients with severe GH deficiency. Data were collected biannually from medical records through 2009. Baseline DXA measurements were available for 414 patients; 71 (17.1%) had osteoporosis at one or more of the measured sites; 147 (35.5%) had osteopenia.

During a mean follow-up of 5.2 years, researchers found that 166 of patients with previous NFPA were prescribed osteoporosis medications (21.3%), as were 69 patients with previous Cushing’s disease (38.5%) and 22 patients with previous acromegaly (33.4%). During follow-up, 39 patients experienced fractures (3.8%; 32 experiencing one fracture), including 26 patients in the previous NFPA group, eight patients in the previous Cushing’s disease group and five patients in the previous acromegaly group. The median time between baseline and first fracture was 2.4 years (mean age, 59 years).

Researchers found that fracture risk did not differ between groups before 6 years’ follow-up. Fracture risk increased in patients with previous acromegaly after 6 years’ follow-up, but not for those with previous Cushing’s disease vs. patients with NFPA. Results persisted after adjustment for multiple factors, including sex, age, fracture history and the extent of pituitary insufficiency.

The researchers noted that patients with previous Cushing’s disease were younger and more often women and had a greater history of osteopenia or osteoporosis, whereas patients with acromegaly had a longer duration between tumor treatment and the start of GH therapy and were treated more often with radiotherapy.

“The increased fracture risk in the present study may be a long-term effect of impaired skeletal health due to previous GH excess, even though this was not reflected by an increased occurrence of osteopenia or osteoporosis in the medical history,” the researchers wrote. – by Regina Schaffer
